Anyone can become a hostage of annoying noise. Just as anyone can be a victim of noisy neighbors, so too can they become the cause of their anxiety. The solution to the painful problem is ceiling insulation. Modern technologies are constantly offering new types of materials that contribute to the absorption of sound waves. Noise isolation of the ceiling in the apartment under the stretch ceiling is not particularly difficult, but requires careful study of the basic concepts.
Soundproofing the ceiling in the apartment: the advantages of a stretch ceiling
By itself, suspended ceiling already involves a certain percentage of noise insulation. According to experts, it “extinguishes” about 5 dB. The airspace between it and the concrete slab reduces the propagation of sound waves. Attaching it to walls, not to floor slabs, also reduces sound propagation. Of course, the airspace is inherent in suspended ceilings. But here the profile system itself, on which drywall is mounted, will serve as a bridge for sound distribution.
It often happens that only this quality stretch ceiling will not be enough. Therefore it is necessary to resort to various methods of solving this problem. Each of these methods is different material selection. It is the material used that will become the fundamental criterion in the whole process of sound insulation of the ceiling. In addition to the choice of material, you need to decide on its thickness. Its indicator in direct proportion reduces the noise in the home. Today’s market offers the latest materials that are able to qualitatively reduce the volume of sounds and not pick up such important centimeters.
99% of the noise reduction efficiency depends on the choice of material. In order to more reliably understand the principle of operation of the entire system, it is necessary to define and distinguish between two concepts. Materials are sound-absorbing and soundproof.
Sound absorbing The material has a fibrous, porous, soft structure. At first there is a braking, and then a full absorption of the sound wave. The fiber of which they are composed, with its properties, provides the desired result. These include mineral wool, basalt type of slabs, felt and sinteponovye plates.
Soundproof – the opposite of the previous form on the principle of action. Such material does not absorb, but reflects sound. It must be tight and strong in its structure to reflect the wave, and it would not be able to shake it. These include brick, concrete, etc.
Helpful advice! The best method of using these or other materials for sound insulation of the ceiling in an apartment will be to use representatives of both categories simultaneously.
Sandwich construction, with sound-absorbing material inside and surrounded by massive sound-insulating material from the outside, is most beneficial in practice. Such a composite structure will significantly affect the noise reduction ratio. Sound absorption generally depends on the choice of material, its thickness and quality. The modern market offers a lot of well-known and well-established products, as well as many new ones just starting to receive feedback: cork, membrane.
Mineral wool – a proven method of sound insulation under a suspended ceiling
Mineral wool is the first in the list of noise insulation materials. It should be noted that its use will give not only this effect, but also other advantages:
- good insulation;
- ease of installation;
- relatively inexpensive price.
The above qualities are very important at the stage of choosing a material. If we talk about the installation of noise insulation of the ceiling in the apartment with your own hands, then you will need to construct a wooden frame. The release form of the insulation coating is a roll or mat. Their width determines the range of distances each rake is from each other. In order for cotton wool to hold tight to the ceiling, it must fit tightly and tightly under the slats. Therefore, the distance between them should be less than the width of the sound insulator. For reinsurance from his fall, experts sometimes practice nailing insulation to nails across its area.
The minus in the technical characteristics of mineral wool is its instability to moisture, under the action of which it swells and loses its shape. The way out of the situation was the use of the following materials in such a sequence: waterproofing film, mineral wool, vapor barrier.
Important! Steam rising from inside the room threatens to damage the sound insulator. Therefore, the mineral fabric must be reliably protected from two sides.
High-quality noise insulation can be organized using a material such as polystyrene foam. It is easy to use, has a low thermal conductivity and vapor permeability. The technological process of its manufacture is the saturation of polystyrene beads with gas, as a result of which they increase in volume by 50 or more times. This increase gives a large coefficient of elasticity, resistance to compression and lightness. Convenience during installation provides its release in the form of plates, whose thickness is from 2 to 10 cm. The sound absorption of expanded polystyrene also has a high level: from 23 to 25 dB. Fastening of polystyrene foam plates to the surface of the interfloor overlap is carried out with the help of special glue, “liquid nails”, and foam. For a stronger grip using attachment- “fungi”.
The latest production technologies in any field provide consumers with the opportunity to choose an alternative option. For soundproofing the ceiling in an apartment under a suspended ceiling, the production of noise insulating membranes was such an option. The noise isolating thin layer of such membranes will effectively cope with its task. Due to its small thickness, they are very advantageous in comparison with mineral wool and expanded polystyrene, which take significant centimeters of ceiling height. Such acoustic membranes are made of natural material aragonite, therefore they have an exceptionally environmentally friendly composition. They are produced in the form of rolls, differ in flexibility and plasticity, nevertheless – this is a rather dense type of insulator. Due to this combination of important technical characteristics, noise-absorbing membranes are becoming increasingly popular.
Special fabric – a new word in soundproofing. The speaker system is a fabric with a huge number of holes. Such microperforation is able to absorb noise perfectly. The sound wave is constantly reflected from each hole. At the same time, it loses energy until it is completely extinguished inside the polymer holes.

Cork has excellent sound insulation properties. In addition, it has several other advantages:
- natural and environmentally friendly;
- has a low thermal conductivity coefficient;
- has a high level of sound insulation (it should be noted that this material absorbs high-frequency waves better);
- soft, elastic, moisture resistant;
- thin, does not “take away” centimeters of height of a ceiling.
It should be borne in mind that when using cork coating for the device of noise insulation of the ceiling in the apartment, the price of the material itself will be quite noticeable. Also need more expensive special glue for mounting this material.
Installation of flow noise insulation in an apartment under a suspended ceiling can occur in three ways:
- laying between the profile of crates;
- fixing with dowels – “fungi”.
The choice of installation method depends on the noise insulation material used, the design of the room, the desired result and the availability of utilities in the subceiling zone (wiring, ventilation, etc.).
Before proceeding directly to the installation surface of the ceiling must be prepared. Bearing plate should be carefully examined for cracks and holes, irregularities. Small gaps are simply spattered, large ones can be sealed with foam. Every seam should be perfectly smooth. After this procedure, the floor should be well cleaned of dust and debris. Often used in any construction area element – primer. It greatly increases the adhesion between the superimposed layers.
Important! Do not forget about lighting. Making a noise insulation ceiling, it is necessary to bring the hook. A chandelier will be mounted on it later.
A separate issue for consideration will be the sound insulation device in a house with wooden beams. It is usually done on the second floor. The floor of the second floor is the ceiling of the first. And any construction manipulation is easier to do with the floor than with the ceiling. The process goes like this: a crate is made of a wooden bar, into the cavity of which a noise insulator is laid. One of these materials is granulated sand. It has excellent sound wave absorption characteristics and is therefore used quite often.
The name of the first method makes it clear that its basis is the frame. Most often for it use a metal profile or a wooden bar. If you believe the reviews, noise insulation of the ceiling in this way makes many.
At the beginning of the work, markings are made along the entire perimeter of the ceiling. Parallel profiles should be about 60 cm apart. The distance from the outermost profile to the wall is no more than 10 cm. Holes are drilled, the entire crate is installed and it is possible to proceed directly to laying the soundproofing material
The frameless method of sound insulation of the ceiling in the apartment is less labor-intensive than the previous one, since it completely eliminates the installation of complex structures. In the course of work, special adhesive mixtures are used. Recently appeared novelties in the field of soundproof materials have a distinctive feature: one of the parties is self-adhesive. Here it will be important to press this side correctly and evenly over the floor slab and everything will be ready in a very short time. This feature is distinguished as the biggest plus when choosing materials for sound insulation of the ceiling in the apartment. Reviews guarantee that spending on their purchase, everyone can significantly save later. Since further installation does not require the purchase of absolutely no additional materials.
The second subspecies of the frameless method is the method of installation of sound insulation using dowels, “fungi”. In its application, rough marking is also required, additional sizing of panels can be used. “Fungi” must be mounted on the corners of the plates and, preferably, in the center.
High-quality insulation of the ceilings in the apartment under the stretch ceiling should be performed as smoothly as possible, without cracks and gaps. This will give the opportunity to get the desired result. Following the above tips, you can make soundproofing ceilings with your own hands. And staying in your own home will bring only pleasure. “Loud” tenants of the upper floor will no longer be disturbed. At the same time, you can be sure that they will not know all the details of your personal life.
